Application filed February 18, 1926. Serial bro/89,181.? 1

This invention relates to implements for cuttingand opening pasteboard boxes or the like and the general obj ectof thein-vention .is-lio provide a device of this, character which is particularly convenient-in opening large and heavy pasteboard boxes and thoroughly effective in use anrl'whiclris provided with .a guide whereby the knife may bepositioned adjacent the corner of the box being cut-land whereby the knife may be d1sosed in a vertical position and prevented from entering to too great a depth into the box being cut.

My invention is illustrated 7 1n the accompanying drawing, wherein I Figure 1 is a side elevation of a box opening implement constructed in accordance with my invention; f Fig. 2 is atop plan view of the structure shown in Figure 1;

Fig. 3 is a section on Figure 1;

Fig. 4 is a section on the line &-4 of Figure 1; v v 1 Fig.6 is a perspective view of themodified form of stop; I Referring to this drawin that my improved implement comprises a handle 10 having extending axially therefrom a shank 11, the shank being bent downwardly upon itself and then extended parallel to the body of the shank, as at 12, and formed to provide a blade 13, the upper edge of which is sharpened and said cutting edge extending downward and forward-at. an angle to a horizontal plane.

Riveted, bolted or otherwise attached to the shank 11 is a plate 14 which is angularthe line 3-3 of ly bent at 15 in a horizontal plane and then downwardly extended, as at 16. Preferably, cut-away, as at 17, down to this horizontal angular portion 15, said out extending 1nward to a point approximately above the point of the blade 13.

Mounted upon the shank 11 or upon the plate 14 is a stop comprising a vertically disposed plate 18 which may tween the shank and plate 1 1, this'plate or equivalent member 18 being provided preferably with laterally extending rollers 19 which are adapted to bear against the upper surface of the body of the box or against the surface upon which the knife or ii plement is being used. While preferably I use rollers 19 as. stops limiting the depresthereof and then the knife turn-ed into .a

g, it will be seen upper ,end of the knife edge.

the forward edgeo-f the plate is be inserted bewish to belimi ted to thisas I may use an angular plate. "Thus the plate,;18 :may be formed with an angular flange '19 .and this flange act-as a stops 1 In the use of this :(leVlCO, the knife is drawndowmvard so as to nsert its 13011 into the wallo'f thebox adjacent the corner horizontal position with the guide flange .15

rest-ing upon the top of the box and the flange 16 extending down against theside of the box, the stop under these circumstances bearing against the top of the box. The knife isthen drawn longitudinally along thebox and the cutting edge of the" blade 13, which intersects the wall to be cut, cuts this wall as the knife is drawn forward. The gauge or stop formed bythe Jrollers 19 or the plate 19 prevent the knife from running too deeply into the box or injuring the contents thereof.

1. An implement for cutting open paste: board boxes comprising a handle, a shank extending therefrom, the shank' being re and a portion adapted to restagainst the side of the box, the first named portion being disposed below and intersecting the inner 2. An implement for cutting open pasteboard boxes comprisingja'handle, a shank extending therefrom and returnedupon itself, this returned portion being formed with a knife blade having its back extending parallel to the shank and having an upwardly facing, upwardly and rearwardly ins clined edge, and a straightlongitudinally extending box engaging guide attached to the shank and extending parallel thereto, the margin of said guide being angularly' bent laterally and then downwardly, the lat erally e'xtendingportion of saidguide in tersecting the upper end of the blade.

3. An implement 'forfc'uttingopen pasteboard boxes comprising a handle, a'shank extending from the handle and returned upon itself and formed with a knife blade having an upwardly facing downwardly and forwardly inclined edge, a box engaging guide attached to the shank andv a box engaging stop attached to the shank and comhavin an unwardl facin downwardlv and forwardly inclined edge, a box engaging guide attached to the shank and a box engaging stop attached to the shank and comprising a plateextending downward from the shank and having a plurality of laterally projecting rollers.

5. An implement for cutting open paste- 20 board boxes'comprising a handle, a shank extending from the I handle and returned upon itself and formed With a knife blade having an upwardly facing downwardly and :lorwa-rdly inclined edge and a box engaging guide attached to the shankand comprising a plate extending downward from the shank toward. the blade, said plate being angularly bent to engage the corner of the boX, said plate'at itsend opposite the extremity of the knife being-cut-away to provide an opening whose'lower Wall is formed by the laterally extending flange, said cut-away portion extending inward to'a point opposite the point of the knife. i

In testimony whereof I hereunto atlix my signature.
